Key Responsibilities
● Lead and mentor a team of 3–4 embedded firmware engineers.
● Understand product requirements and convert them into technical design and firmware architecture.
● Prepare development plans, assign tasks to team members, and ensure timely delivery of firmware milestones.
● Develop and maintain embedded firmware using C/C++ for microcontrollers such as ESP32, STM32, and ARM Cortex M-series.
● Implement and troubleshoot communication protocols such as TCP/IP, HTTP, MQTT, and Modbus.
● Design and develop low-level drivers and board support packages (BSP).
● Work closely with hardware teams for hardware bring-up, debugging, and validation.
● Develop firmware using RTOS concepts for multitasking systems.
● Implement FOTA/OTA firmware update mechanisms.
● Integrate peripherals such as SPI, UART, I2C, I2S, USB, DMA, ADC, DAC, timers, EEPROM, flash memory, SD cards, and Ethernet.
● Integrate sensors such as temperature, pressure, flow, dissolved oxygen, and environmental sensors.
● Collaborate with software and cloud teams to ensure seamless device-to-cloud integration.
● Debug system issues using tools such as oscilloscopes, logic analyzers, and in-circuit debuggers.
● Ensure firmware reliability, maintainability, and performance for field-deployed IoT products. Required Skills & Experience
